What is Diethylamino hydroxybenzoyl hexyl benzoate CAS 302776-68-7?
2-Ethylhydroxybenzoylbenzoic acid dimethyl ester is an organic peroxide that has a strong oxidizing effect. During thermal decomposition, it is prone to generating highly reactive free radicals, which makes it thermally unstable. It may decompose at relatively low temperatures. During the decomposition process of 2-Ethylhydroxybenzoylbenzoic acid dimethyl ester, a large amount of heat and gas are released, causing the temperature to rise and accelerating the decomposition. These gas substances can form sufficient pressure within the sealed packaging to damage the packaging, and subsequently, explosions and fires may occur.
Diethylamino hydroxybenzoyl hexyl benzoate CAS 302776-68-7 Use
3.5 liters of dichloromethane, 355 grams (1.35 moles) of 2-hexoxy carbonyl benzoic acid (VII), 17.17 grams (0.139 moles) of 4-dimethylamino pyridine, and 333.8 grams (2.02 moles) of 3-diethoxybenzyl phenol (X) were added to a 5-liter four-neck round-bottomed flask and immersed in a hot bath. The apparatus was equipped with a mechanical stirrer, a thermometer, a dropping funnel, and a cooler connected to a calcium chloride tube. The solution was cooled to 20-25°C. Slowly added 321.6 (1.55 moles) of cyclohexyl carbodiimide. The resulting mixture was stirred at 20-25°C for 4 hours. The total conversion of 2-hexoxy carbonyl benzoic acid (VII) was monitored by thin-layer chromatography (Cl3CH:AcOEt; 80:20). The formed cyclohexyl urea was filtered. The filter cake was washed with 530 milliliters of dichloromethane. The dichloromethane solution was washed with 1.79 liters of 2N sodium hydroxide water solution. The mixture was concentrated under reduced pressure. The resulting oil was dissolved in n-heptane. It was washed with 1.2 liters of 4N acetic acid, 300 milliliters of 20% sodium carbonate water solution, and 600 milliliters of water. The solution was colored by stirring with activated carbon. The colored solution was filtered. The mixture was concentrated under reduced pressure to obtain 2-ethyloxy carbonyl benzoic acid phenyl acetoxybenzoic acid hexyl ester.
